line number question

[Marge Inoferror]

Well, 2 questions, actually...

I get an error when my form's window gets covered by another window. I can resize sucessfully all day, but when the window is covered by another window - it bombs Here is the error:

Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object.
at Talk.Form1.OnPaint(PaintEventArgs e) in g:\talk\form1.cs:line 244

One question would be - any ideas on what to look for as far as the source of the error is concerned?
The other question is - is there a way to find where line 244 is in the source code (other than counting the lines)?

Thanks,
Marge

Marge,

As the the first question ... the source of the error is the form's OnPaint event. That is not likely to be a very large amount of code. To get to the exact line, simply choose Edit | Go To ... and specify the line number. Or watch the status bar as you scroll through the file, for the current line number.

Of course your question suggests you aren't using Visual Studio, but we aren't into guessing ... the more info you provide the more we can help.

Thanks, Bob

I was asking about Visual Studio.net. Are there other development platforms for C# / dotnet ?

You can write C# in any editor, however there is atleast SharpDevelop and I
think Eclipse has a C# plugin, though I believe it isn't terribly well
regarded.

Yes, and there is also Borland's C# environment, whose name eludes me at the
moment.

Ya, C# Builder I think. That would keep it inline with their other products
anyway. Forgot about that one.
